Natural convection in inclined partitioned enclosures

Effects of thin fin on natural convection in porous triangular enclosures

“…As dimensionless fin height increases, the value of extreme stream-function decreases since increasing of the partition height presents an obstacle for flow field. This observation is supported by BenNakhi and Chamkha [30]. However, the values of smaller Rayleigh number and the values of extreme stream-function do not follow this trend due to quasi-conductive regime.…”

“…Many researchers studied the problem of divided rectangular or square nonporous enclosures with partition. The partition length, thickness and location centers are governing parameters for heat transfer as shown by Turkoglu and Yucel [27], Zimmerman and Acharya [28], Dagtekin and Oztop [29], Ben-Nakhi and Chamkha [30], Hasnaoui et al [31], Yucel and Ozdem [32], Dagtekin et al [33], Oosthuizen and Paul [34], Bilgen [35]. These studies are analyzed for rectangular or square shaped geometries and non-porous medium.…”

Non-Darcian Effects on Buoyancy-Induced Heat Transfer in a Partially Divided Square Enclosure with Internal Heat Generation

“…Therefore, natural convection heat transfer and fluid flow in partially divided enclosures has been the subject of many studies in the last few decades because of its importance in many engineering applications (Chu et al 1976;Flack and Turner 1980;Bar-Cohen 1987;Bergman and Petri 1998;Du and Bilgen 1992;Al-Amiri et al 2009;Corvaro and Paroncini 2009). A detailed study of flow and heat transfer phenomena in partitioned enclosures is useful in understanding the processes that occur in natural convection flows in passive solar heated building, solar collector design, cooling of heat generating components in electronic packages, cryogenic storage, crystal growth, fire prevention, semiconductor production, and nuclear industries (Ben-Nakhi and Chamkha 2006). Enclosures with a single or double divider have been widely investigated in the literature, especially for enclosures filled with a viscous (Newtonian) fluid.…”

Numerical analysis of natural convection and entropy generation in a 3D partitioned cavity

“…Hussain et al [10] studied the effect of the length and location of one partition attached in the bottom of a particular cavity having an adjacent inclined single cold wall and gave the variations of the Nusselt number with different conditions of wall inclinations and partitions locations. BenNakhi and Chamkha [11] put in evidence the effect of the inclination angles and the partition lengths on the natural convective heat transfer and the fluid flow inside an inclined enclosure equipped with partitions; they predict an average Nusselt number decreasing with the increase of the inclination angle beyond 30°, and show that the average Nusselt number increases with Rayleigh numbers and the flow speed decreases with the increase of the partitions length.…”

“…This parameter was studied by several researchers like Amraqui et al [32] and Ben-Nakhi and Chamkha [11], but the most important study has been made by Heidary [33] who combined the study of the inclination effect of the partitioned cavity with the effect of the length and location of partitions on the heat transfer, fluid flow and entropy generation. The study is made numerically on twodimensions.…”
